Product Description

The Series 2200 Card Cages result from a packaging concept which has been designed specifically to accommodate fiber optic related devices. Each fiber optic module has its fiber optic connectors positioned so as to minimize the bend radius and stresses on the fiber cable. In addition, ample room has been provided to allow the dress of the optical cable out the bottom of the card cage. This can be used to harness the cable or, it can be used with Telebyte's junction adapter drawer as the point where patch cables are transitioned to the incoming fiber cable. With this unique design concept all fiber cables are protected and cables cannot protrude beyond the front surface of the rack.

The card cage accommodates either AC or DC power supplies. The AC power supplies are of the universal switching type and therefore are directly compatible with 110 Volts, 60 Hz, or, 220 Volts, 50 Hz. The DC power supplies operate from -48 Volts to accommodate Telco applications. The basic card cage is equipped with either an AC or DC power supply. Redundant power is easily added by plugging in another supply. Each power supply has its own fan and a separate power input, therefore, separate power feeds can be provided to increase the reliability of the entire system.

To enhance network reliability each power supply is equipped with extensive alarm circuitry which can be remotely monitored. Any alarm condition will activate both audible and visual alarm indicators. In addition, an alarm will also provide a contact closure on the rear panel of the card cage for use by other network management systems. The alarm conditions monitored are a power supply failure or an alarm generated by any of the modules resident in the cage. Audible alarms may be reset, however, visual alarms can only be cleared by eliminating the alarm condition.

In addition to the dual power supplies the card cage accommodates a total of 16 modules. Each module slot has a fixed address in order to facilitate future network management and diagnostics. Each plug-in module, including the power supplies are locked in position when they are inserted into the cage. Modules are easily removed by rotating the locking bar. There are no screws, fasteners or tools required for module insertion/removal. The user interface, for each module position on the connectorized backplane, includes a female DB-25 connector, an RJ-45 connector and a 5 position terminal block. There is an additional terminal block for the alarm relay contacts.

The backplane also includes a communications bus that connects all modules and power supplies. This feature will allow enhanced network management features to be implemented in the various modules.
